PPP Multilink not distributing correctly

I have a problem when a PPP Multlink bundle forms on a 3640 with 12.2(13)T5 . The minimum numbers of channels connect as configured but the load is not distributed accross those channels with only 1 left carrying to full capacity.

This problem only occurs in one direction then other direction is fine.

Direction placing calls - not distributed

Direction receiving calls - OK

See chan 22 loaded and 19 not

Bound to:

Interface is bound to Di1 (Encapsulation PPP)

Re: PPP Multilink not distributing correctly


May be the problem due to "Netflow" switching because you have informed that only TX is not balanced out.
